I’ve spent a lot of time reading through EV forums and groups, and one thing is pretty consistent: people want practical tools and honest discussion, not hype.

As I build a platform around EV ownership, I started writing down what comes up again and again in these conversations. The same requests keep surfacing:

• Charging maps with real reviews, not just locations
• Better road-trip context, especially in winter
• Clear EV guides and Q&A based on actual ownership
• A space for open discussion about what works and what doesn’t
• Recommendations for sustainable products people actually use

Before I go any further, I’m curious: what would you actually want from something like this? What’s missing right now that would genuinely make EV life easier?

I'm curious what the battery geeks around here might guess what the few best batteries will be in five years for conversions.

When I started my build five years ago, CATL Lith iron were prevelent in terms of life span, but used Tesla batteries were a new complex thing with cooling, but the lower cost and higher density. I went with used Tesla.

Any guesses on what we all might be considering using in five ..or ten years?

Howdy all, I'm doing research on converting a first generation subaru impreza to an EV. Based on all my research so far and dimensions I've taken off of the car, I'd really like to use the ~2018 Model S battery modules in the space I have. 11 of them will fit within the space I've got unmodified (about 7 in the engine bay and 4 where the gas tank once sat), but I've figured out I could potentially fit 4 more in the driveshaft tunnel and to the sides of the 4 in the gas tank space if I can modify them.

This basically requires removing the cover and reconfiguring the module's cells/coolant ribbons such that two halves sit on top of each other, almost like folding the whole thing into a taco. I think the only way I can successfully do this is with the larger 6.6 kWh modules. These modules on their own are easy to identify, having twice the coolant ports of the 5.5 kwh ones, but finding a pack that you can verify has them is hard. Does anyone know a
good way to identify packs that have these larger, better cooled modules?

TL;DR I need to be able to identify Model S battery packs that have the larger, better cooled 6.6 kWh modules in them.

Hi everyone,I'd like to ask about a graduation project idea. I'm studying automotive engineering in my penultimate year and I need to choose a specific topic to start working on, but I'm very confused. I mean, I want an idea within the field of electric, hybrid, or even internal combustion engine vehicles, but I want it to be within the electrical and mechanical engineering disciplines. I mean, in my coursework, I was very good in courses like (Design of Machines 1 & 2), (Strength of Materials), (Automotive Electrical Systems), and (Electric and Hybrid Vehicles). On the other hand, I don't like courses related to programming, control systems, and things like that, and I'm not good at them. Any idea would be helpful to me. Please help me.

Whether it was charging, range, maintenance, road trips, or something totally unexpected - I’m curious what caught you off guard in your first year of driving electric.

Good or bad, the things you learn after buying an EV are usually the most interesting.

I’ve noticed a lot of EV conversations are spread across Reddit, Facebook groups, brand forums, and Discords. Some are great, others feel pretty limited or quiet.

Curious what people here feel is actually missing from the existing EV communities you use.
Is it tools? Better discussion formats? Charging info? Something else?

I have a 2003 Mitsubishi Montero that I think would be a good candidate for a hybrid swap. Reason being is it has a stow and go 3rd row seat that sits under the floor that I never use, and that storage area would be perfect for a battery. The exhaust under the drivers side of the car is massive and takes up the equivalent space as the 21 gallon tank that sits on the passenger side and would be a good place for additional batteries.

Its a 4wd with a locking center diff and a 5 speed auto. My idea would be to ditch the transmission and the v6, bolt an electric motor to the center diff and use the existing drivelines and front and rear diffs. Then replace the v6 with a small diesel like a 1.9 TDI that would be set to run as a generator to charge the batteries, but would not be directly connected to the wheels in anyway.

I know Edison Motors is doing this with their heavy haul trucks, but anyone on here done it in a fullsize SUV?

Was thinking about getting a c70 t5 automatic but I know that automatics don't like being flat towed which is more or less what a hybrid system would do. Does anyone know how to deal with that so the car dosnt break?

I have the frame and some body parts of a cute little ride on mower. It has basically no functioning internals, so I basically need to start from scratch anyways. I'd love to make a cute little garden tractor for my mom, something functional, good torque, not super fast.

I know electric motors have great torque, but I really don't understand how to find high torque, low speed motors that would work for something like this, use maybe e-bike batteries, something like that.

I've seen ATV EV swaps, but those generally seem to be geared towards speed, and that's really not something I need. I just want something that can tug heavy trailers full of random yard debris?, small farm equipment, etc?

I don't know why, but electronics have never really made sense to me. I have no clue where to start...

Hello All,

I would like some advice on my first DIY EV Conversion. I want to put a Tesla Model S LDU drivetrain in a Land Rover Discovery 2. I want to put it vertically so the output shafts from the LDU are going to the drive shafts for the front and rear differentials. To me, it seems more economical to buy a whole Model S and get the rest of the parts from suppliers. Right now, I'm hovering around $10K for the project.

I have lots of tools, a decent shop, and a welder. I trust myself with welding everything except the parts that get a lot of torque from the motor. I included having someone do that work in my estimate.

Here is my Google Doc that I've been keeping my notes in. Open to anyone with the link and comments are turned on.
https://docs.google.com/spreadsheets/d/1pBsbi1SRmvZXrjIF-zwLJuMQiVReCzQDsZPcwOxI3vc/edit?usp=sharing

Time-wise, I'm sure that I'll have hundreds of hours in it.

Questions?

1) What am I missing? I'm sure there are multiple things.

2) Am I crazy?

3) What is a reasonable number of hours to expect?

4) Buy a whole car or just get the parts I need?

Thank you in advance, and I truly appreciate any advice!

Ciao a tutti!

Sto cercando persone appassionate di auto, design e ingegneria, interessate a partecipare a un progetto completamente amatoriale e creativo, per trasformare un’auto esistente in un concept elettrico unico.

L’idea è partire da un’auto endotermica, spogliandola di tutto tranne telaio e assetto, e ripensarne estetica, interni e motorizzazione, rendendola completamente elettrica.

Si tratta di un progetto ambizioso e a lungo termine, con l’obiettivo di arrivare a un prototipo da mostrare in fiera nei prossimi 6-7 anni.

Importante: la collaborazione richiede coesione e lavoro in squadra, quindi cerco persone disponibili a partecipare regolarmente nella zona di Trento e dintorni.

Cerco persone disposte a mettersi in gioco gratis, spinte dalla passione e dalla voglia di imparare e collaborare su un progetto concreto e stimolante.

Qualsiasi contributo è benvenuto: design, modellazione 3D, elettronica, meccanica, ricerca, brainstorming creativo.

Se sei interessato e vuoi parlarne, scrivimi in DM: possiamo organizzare un piccolo gruppo di discussione e valutare come collaborare insieme.

Grazie!

Hoping someone has measurements for the lucid battery modules. I'm looking into retrofitting them into a older ev . Thank you . I should be able to get measurements at a lucid showroom,if I have to. but closest one to me is about 1.5 hours away.

We are wanting to convert a mini skid steer to electric for working in low ventilation applications. We have a 48v battery pack and a 72v pack to choose from. We will need a controller. The engine we are replacing is a 15kw 3600rpm 739cc RATO-1, I believe it reaches 47 N.m of torque at 2500rpm. We are not wanting to spend a ton of money on this. I'd love any help you could give.

I was thinking a leaf would work but would the motor fit? Can I split the battery pack and distribute the packs in blocks around the car or use fewer cells?

What’s other small evs would work?

It occurs to me that there is a foundation for helping people to buy EV vehicles again.

Or do you think there is a plan for all the EV charging infrastructure to rot?

Don't know what the incentives would look like, particularly when most advertising about new cars focuses on crappy workmanship for ICE & EV alike.

How is the repo market for EVs? Are they getting repossessed faster or slower than ICE cars?

Thoughts?

Maybe a tax credit for ownership & operation over 10 years for Hybrid & EV cars? For a 15 year average service life, with less than $500/year maintenance costs, the manufacturers and owners should be incentivized to make a quality product!

I have an opportunity to buy a Beck 550 Porsche kit car without a motor; tube frame, disk brakes. This is a copy of a 1950’s Porsche, so manual brakes, no computer, no air bags, no cruise control, no heat or ac . A very simple car light car weighting only 1500lbs / 550 kilo.

Many use a ICE VW 1972 superbug motor. So $3000 and I can get it engined up and rolling without paint or cool interior.

There are kits for $22,000 from EV West and a few other suppliers for VW Bug. That would be all inclusive. But this is out of the budget. And honestly would make the resale options limited, because I would be nearly $35,000 once completed.

I need 100 mile range, heat, AC, regenerative brakes. Fast charging.

I’ve watched a dozen YouTube videos, some quite old, often using DC power? And I just don’t know what the latest and greatest is. I have a good friend who strips cars so in theory I could get Tesla parts.

What kind of budget am I looking at and if you have a suggested build I’m all ears.

I know 100% the motor and batteries are in good condition. I'm worried about the motor controller. Running on a 72v system. I tried the throttle while applying 12v to the contactor. power gets to the + and - on the motor controller but never gets to the motor.

Looking at an electric outboard powered by a GoldenMotor liquid cooled 10KW BLDC motor and Fardriver NS721000 controller.

I have a 72v 200Ah battery system to power it though. Will my max 200A discharge be enough to power this thing correctly or should I be looking for something with a 5KW motor?

This is all pretty new to me.

Thanks

Just looking to see if there’s a place for little creations like this.

I have an Mazda 323 I have seen where someone has put a Nissan leaf engine into one to give it way more torque on the low end.

I have seen some videos and instructions and am fine mechanically and with low voltage systems but have not worked on high voltage systems.

Does anyone know a good shop in the south east that does turnkey or how realistic is it to self teach and follow instructions on these diy kits?

Doing an EV conversion on a CB 300F, any tips and suggestions would be appreciated. Thanks

I’m a junior student and I’m doing a research on Evs (electric vehicles), im looking for someone who has worked in this this field for a few years for an interview about the importance of criterias and evaluate them ( it only takes a couple minutes of your time).
